The 40-year-old actor - who split with the former 'Friends' star after 11 years of marriage in October 2010 - was spurred on by estranged wife and Coco, seven, who cheered him on from The Front row as he hit the dancefloor with professional partner Kym Johnson.

Performing a Viennese waltz, David and Kym received a standing ovation from the audience and a whole host of compliments from the show's judging panel, made up of Len Goodman, Carrie Ann Inaba and Bruno Tonioli.

Len said: "I was very impressed. You're a dancer."

Following the routine, David - who received a score of 18 for his moves - said of daughter Coco: "She's just so beautiful. She's the love of my life."

Meanwhile, Cher's son Chaz Bono - who was born a female named Chastity and began gender reassignment surgery around three years ago - received equally positive comments from the judges on the debut night of 'Dancing with the Stars', attaining a score of 17.

Dubbed "Razzmataz Chaz" by Len, Bruno added: "So cuddly and cute. Great, great debut, Chaz. You should be proud."
